To find 8x397, I used the stack method.
a.) 397
<u> x 8 </u>
3176
b.) This method works best because it's easy to do, and the factors aren't too big to multiply by hand, unless it was like a billion times a million. But in this case, it's not, so it's perfectly fine to use the stack method.
I hope this helps and have a good night! :D
Answer:
<h2>(1, 1)</h2>
Step-by-step explanation:

If you would like to find a pair of equations that best models the relationship between p and d, you can do this using the following steps:
p is 2 more than d ... p = d + 2
p is 1 less than d ... p = d - 1
The correct result would be p = d + 2 and <span>p = d - 1.</span>
